The first hot air balloon was built by the Montgolfier brothers, Joseph-Michel and Jacques-Étienne, in 1782. Their initial experiments began in the early 1780s, culminating in the first successful flight of a balloon made of paper and linen in September 1783. This balloon was launched in Annonay, France, and marked the beginning of human flight in hot air balloons. The entire process from conception to the first flight took about two years.
Building a hot air balloon can take anywhere from a few weeks to several months, depending on the complexity of the design and the materials used. It involves tasks like sewing the fabric envelope, assembling the basket, installing the burner, and conducting safety checks before the balloon can be flown.
Air expands when it is heated. This makes it less dense than colder air. Hence, it has buoyancy, and tends to rise. If it is trapped in a balloon, it can take the balloon up with it, along with things attached to the balloon, as long as the buoyancy of the balloon exceeds the attached weight.

To launch a hot air balloon, the pilot first inflates the balloon with a large fan to fill it with cold air. Then, a burner is used to heat the air inside the balloon until it becomes hot and the balloon starts to rise. Once it is fully inflated and upright, the passengers can board and the balloon will take off.
it took about a year for the first hot air balloon to be made.
